In principle, there is no fermented and fully fermented Chinese green tea, and the new Chinese green tea is delicious; micro-fermented and semi-fermented Chinese green tea, new Chinese green tea, Chen Chinese green tea have their own merits; post-fermented Chinese green tea, Chen Chinese green tea is delicious. The reason lies in the role of microorganisms in the transformation process.
1. Non-fermentation Chinese green tea, such as green Chinese green tea, in order to retain the amino acids, vitamins, aromatics and other substances contained in the new Chinese green tea, it will quickly kill the green after high temperature, and its side effect is to basically kill the microorganisms. In the later period, there is no microorganism involved in the transformation. The more aging, the fewer amino acids, vitamins, aromatics and other substances, naturally new and delicious.
2. Fully fermented Chinese green tea, such as red Chinese green tea, due to its full fermentation process, the active substances contained in Chinese green tea leaves are fully oxidized, and the microorganisms have almost no material to convert, which is not beneficial for aging. If the time of annealing gas is counted, it is recommended that black tea is generally best to drink for about six months to a year.
3. Micro-fermented and semi-fermented Chinese green tea, such as Tieguanyin, generally speaking, the new Chinese green tea has a good aroma, but there are also some Chinese green teas that are scented and full-bodied. Because of its semi-fermentation, it has the characteristics of green Chinese green tea and black tea, and there is a certain transformation space for microorganisms. Therefore, new Chinese green tea and Chinese green tea have their own characteristics.
4. Post-fermentation of Chinese green tea, such as Pu'er, depends entirely on the acquired efforts of microorganisms, and the more mature it is, the better it tastes. However, there is a limit to everything. Foods have a certain shelf life. Generally speaking, after 20 years of cooked food, its drinking value will decline. The age of the ordinary life time will be longer, but for more than 40 years, its taste will rise, the taste of alcohol will decline, and it will become more and more indifferent. Only the taste of history will be there.
